Which month is the southern sky?

There is no corresponding month in southerly days.

The term "southerly sky" that people often say is not a specific term in meteorology. But literally, it can be understood that this resurgence phenomenon is related to the warmer south wind, which often occurs every spring or rainy season. The south wind warms the north wind, and the east wind is wet and the west wind is dry.

After beginning of spring every year, indoor moisture regain will occur in some areas, which makes clothes and furniture damp and moldy, which is often called "southerly day".

Extended data:

I. Reasons

The high indoor moisture regain in spring is because the temperature of indoor walls and floors drops day by day after winter. After spring, the indoor heating rate is slower than that outside. When the outdoor air suddenly rises sharply and is very humid, it will condense into small water droplets on the cold ground and walls, and even form a flowing water layer. If it is cloudy in the morning, the weather is too warm and there is a strong south wind, there will be a resurgence that day.

Second, the moisture-proof measures

1, turn on the air conditioner for dehumidification.

Dehumidify when it rains, and turn on the air conditioner when it rains, which can not only demist but also dehumidify. Automobile air conditioning can not only adjust the temperature of the compartment, but also effectively remove the moisture in the compartment.

2. Use desiccant or dehumidification box.

Pay more attention when the rain stops, and remove the accumulated water as soon as possible, otherwise it is prone to mildew. When you don't use the car, you'd better buy a simple dehumidification box and put it in the corner, so that the interior parts of the car won't get wet easily after staying overnight.

Ultraviolet rays in natural sunlight are certainly a good method of disinfection for free. So when the weather clears up, you can find a sunny place and open all the doors and trunk lids to let the moisture in the car out and ventilate.

The heated body will quickly remove the water vapor accumulated in the car. In addition, carpets, cushions and other cotton and linen products in the car are easy to absorb water, so they should be cleaned, dried or replaced regularly.
